Tabasco (Spanish pronunciation: [taˈβasko] ), officially the Free and Sovereign State of Tabasco (Spanish: Estado Libre y Soberano de Tabasco), is one of the 32 Federal Entities of Mexico. It is divided into 17 municipalities and its capital city is Villahermosa.
It is located in southeast Mexico and is bordered by the states of Campeche to the northeast, Veracruz to the west, and Chiapas to the south and the Petén department of Guatemala to the southeast. It has a coastline to the north with the Gulf of Mexico. Most of the state is covered in rainforest as, unlike most other areas of Mexico, it has plentiful rainfall year-round. The state is also home to La Venta, the major site of the Olmec civilization, considered to be the origin of later Mesoamerican cultures. It produces significant quantities of petroleum and natural gas.
The state is located in the southeast of Mexico, bordering the states of Campeche, Chiapas, and Veracruz, with the Gulf of Mexico to the north and the country of Guatemala to the south and east. The state covers 24,731 square kilometres (9,549 sq mi), which is 1.3 percent of Mexico's total.[8][9] The northwestern portion is on the coastal plain of the Gulf of Mexico with the south and east as part of the mountain chain that extends into northern Chiapas. It is divided into seventeen municipalities. There are 36 communities designated as urban, with about 3,000 smaller towns and villages. 185 are classified as "regional development centers".[10] Tabasco has seventeen municipalities: Balancán, Cárdenas, Centla, Centro (Villahermosa), Comalcalco, Cunduacán, Emiliano Zapata, Huimanguillo, Jalapa, Jalpa de Méndez, Jonuta, Macuspana, Nacajuca, Paraíso, Tacotalpa, Teapa and Tenosique.
In 1994, the state was officially divided into two regions and five sub-regions for socioeconomic development and geographic documentation. The two major regions are called the Grijalva and the Usumacinta. The Grijalva Region is named after the river on which most of the municipalities here are dependent. It is the smaller of the two regions with a territory of 12,069.34 square kilometres (4,660.00 sq mi) or 48.94 percent of the state's territory; however, it contains most of Tabasco's urban population as well as of its socioeconomic and political activity. It is divided into three sub-regions called Chontalpa, Centro and Sierra; it includes the municipalities of Huimanguillo, Cárdenas, Comalcalco, Cunduacán, Paraíso, Jalpa de Méndez, Nacajuca, Centro, Jalapa, Teapa and Tacotalpa. The Usumacinta Region is named after the main river on which the Centla, Jonuta, Emiliano Zapata, Balancán and Tenosique municipalities depend. It is divided into the Pantanos and Ríos subregions, which are both more rural than the Grijalva Region.[11]
The environment of the state consists of extensive low-lying floodplains, mountains and valleys.[12] Most of the territory is covered with tropical rainforest and wetlands. There are also areas with savanna, beaches and mangrove forests. Much of the rainforest has suffered degradation due to over-logging and conversion of territory into farmland. The east is formed of low humid plains formed by sediment deposited by a number of rivers. In the Chontalpa zone and in parts of the municipalities of Centla and Jonuta, there are swampy depressions extremely vulnerable to flooding from both riverflow and from excessive rainfall.[10] In the south there are some elevations which are part of the central mesa of Chiapas. The most important of these is El Madrigal, La Campana, La Corona, Pomaná, Coconá, Mono Pelado and El Tortuguero. However, most hills in the state do not exceed 30 metres (98 ft) above sea level.[10]
Tabasco has 198.8 kilometres (123.5 mi) of shoreline, 29,800 hectares (74,000 acres) of estuaries, lakes and numerous rivers and streams.[13] Flooding is a frequent occurrence, especially in September and November.[10]
There are four principal ecosystems in the state: tropical rainforest, tropical savannah, beaches and wetlands. Tropical rainforest dominates most of the state due to the high levels of rainfall the area receives. However, what exists today is only a fraction of what used to be, as much of the forest area has been over-exploited by man, mostly through logging and slash-and-burn agriculture. Most of the intact rainforest is found in the municipalities of Tenosique, Balancán, Macuspana, Teapa, Tacotalpa, Cárdenas and Huimanguillo.
These rainforests contain species such as mahogany, cedar, numerous types of palm, jacarandas, ceiba, Salix and many more. There are various types of orchids, bromeliads, tillandsia, ferns, and aroid plants native to the state, along with a variety of species of cactus, both terrestrial-arid and epiphytic-forest types. Examples include Epiphyllum anguliger, Schlumbergera, and Disocactus. This state also has one of the widest varieties of wildlife in the country, such as macaws,
